feature for HBAs that rely on libsas to manage SATA devices.

If you move this in front of:
static const struct scsi_host_template aic94xx_sht = { };

I think that you can remove the forward declaration.

Same comment as for mvs_sht. Perhaps mvs_sht can be moved to the bottom
of the file (in a separate patch series) so that all forward declarations
can be removed?
